Embodiment Construction

[0014] In order to further understand the invention content, characteristics and effects of the present invention, the following embodiments are cited hereby, and detailed descriptions are as follows in conjunction with the accompanying drawings, please refer to figure 1 .

[0015] Such as figure 1 Shown:

[0016] The chemical composition of the alloy material in terms of mass percentage is: silicon 0.44-0.48; magnesium 0.68-0.74;

[0017] Iron ≤ 0.15; Boron ≤ 0.06; Mixed rare earth (La+Ce) ≤ 0.15; the rest is aluminum. That is, on the basis of conventional aluminum-magnesium-silicon systems and gold, a new type of heat dissipation alloy material suitable for press-fit module heat sinks is developed. That is to maintain an appropriate ratio of magnesium and silicon as the main alloying elements, so that the mass ratio of magnesium to silicon is slightly less than 1.73 (for example, the ratio of magnesium to silicon is 1.65). Dissolving in the aluminum matrix increases its ...

Abstract

The invention relates to an Al-Mg-Si aluminium alloy material for a pressed module radiator and a machining process thereof, wherein the alloy material comprises the following chemical ingredients in percentage by weight of: 0.44-0.48 of Si, 0.68-0.74 of Mg, less than or equal to 0.15 of Fe, less than or equal to 0.06 of B, less than or equal to 0.15 of mischmetal (La+Ce), and the balance of Al. The machining process of the pressed module radiator which adopts the Al-Mg-Si aluminium alloy material comprises the following steps of: firstly, smelting and alloying to reach the ranges of the chemical ingredients; secondly, extruding a round cast ingot and carrying out homogenization treatment; heating to 560 DEG C and preserving the temperature for 8 hours; thirdly, extruding and carrying out online solution hardening with the outlet temperature of an extruded section more than 510 DEG C, and air-cooling or mist-cooling; and finally, carrying out artificial ageing heat treatment on a radiator module subjected to the pressing working procedure, heating to 160 DEG C, and preserving the temperature for 8 hours. The invention has the advantages of simple method, convenient operation, improved thermal conductivity and ensured mechanical properties, such as the strength and the hardness, and the like of the product.

Description

technical field [0001] The invention relates to an aluminum alloy material for a radiator and its processing technology, in particular to an aluminum-magnesium-silicon-based aluminum alloy material for a "press-fit" module radiator with good thermal conductivity and guaranteed mechanical properties such as strength and hardness and its processing technology . Background technique [0002] As we all know, the rapid development of electronic technology and its wide application in various fields have made people pay more and more attention to the reliability of electronic products. Thermal environment is one of the important factors affecting the performance and reliability of electronic products. Among them, the high-power module radiator for frequency converter is a special function supporting product of frequency conversion technology, which is realized through the special deep processing technology of aluminum alloy extrusion process and "pressing" process. The currently u...
